WAT'CHOASEI 'Application'filedlnecember 16, 1927. Serial 'No. 240,366.

This invention relates to an improvement in watch cases of the wristwatch type and has for its object to provide a case so constructed thatthe various parts which go to make up thecase shall have movementwith respect.

to one another whereby the case may readily conform itself to the curvature of the wrist and may, be. worn comfortably at all times.

At;the present time, the wrist watches of certain typesare made in elongated form so that certain partsof the same are. likely to protrude beyond the sides ofthe wrist and render the case. awkwardin appearance as Well ascausingit to improperly fit the wrist curvature. 1

The object of my invention therefore, is to hinge certain protruding parts of the case, particularly the strap-receiving parts, with respect to the body of the case so that these parts may incline and follow'the curvature of the wrist.

With these objects and such other objects as may hereinafter appear in view, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Referring to the accompanying drawing,

Figure 1 is a plan view of a watch case made in accordance with my invention;

Figure 2 is a side elevation of the same;

Figure 3 is a plan view of one of the strapreceiving members prior to the installation therein of the hinge member;

Figure 4 is a sectional view on the line 4-4 of Figure 3;

Figure 5 is a plan View of the hinge member;

Figure 6 is a sectional view on the line 6-6 of Figure 5;

Figure 7 is a plan view of the cover plate for the member shown in Figure 3; and

Figure 8 is a sectional view on the line 8 of Figure 1. I

Throughout the various views of the drawings, similar reference characters designate similar parts. I r

In the embodiment of my invention disclosed in the accompanying drawing, 1 indicates the body of the watch case which may be of any desired shape and is provided with a beveled or inclined marginal edge portion 2. Located at a slight distance fromthe opposite edges 3 and 4 of the case are shown the wrist-strap-receiving members 5 and 6. Each of these members 5 and 6 are s1m1lar in construction so a descriptlon of one Wlll suflice.

Each of said members is composed of a hollow trough-shaped casing 7 which is provided with a longitudinal part 8. This part 8 is provided with an outer upstanding. flange 9 and an inner shorter but higher flange 10. The-part 8 is provided with a pair of laterally extendingprojections 9 each of which is enclosed by side flanges 10. These parts 9 are connected by a cross-bar 11 which receives thewriststrap or ribbonlQ. If desired, the cross-bar llvmay be made removable to facilitate the attachment of the wrist strap 12.

At 13 is shown a hinge member which consists of apair of spaced strips 14 having one of, their ends curled or bent downwardly as at 15, the inner terminations of said curled parts 15 being connected by an integrally formed cross-bar 1'6. 7

The two parts 7 and13 just described comprise the two main elements of the strapreceiving member and the hinge therefor and these two parts are connected as follows. The part 13 is placed in position within the trough-like member 17 by positioning the cross-bar 16 in the elongated channel member 8, the two parts 14 protruding out of the cutoutsections 17 located at the ends of the upstanding flange 10. Thereupon the upstanding flange 10 is rolled'or curled over the bar 16 sothat it encloses the same and retains the bar within the casing 7. As is shown in Figure 8, this curling or bending over of the flange 10 is so performed that the member 13 is freely movable or is in other words, hinged to the part 7. Thereupon, a closure plate 18 is placed over the top of the troughshaped member 7. This plate 18 conforms in shape to the entire member 7, in that it is provided with laterally extending ends 19 and is also provided with cut-away parts 20. These parts 20 are lined with the cut-out parts 17 located in the trough-shaped casing 7 so that the strips 14 may protrude and are freely movable without interference by the cover plate. The cover plate is soldered in position and when this is done, the hinge member 13 has the bar 16 completely enclosed and the wrist-strap-receiving member presents the appearance disclosed in Figures 1 and 2. Thereupon the strips 14 are soldered or otherwise fixed to the inclined upper marginal face 2 of the watch case 1.

Through the hinge arrangement disclosed, it will be seen that the strap-receiving members 5 and 6 are freely pivotal to a considerable extent in a downward direction, allowing them to closely conform to the curvature oi? the watch and permitting a wrist watch to be made in an elongated form without presenting an awkward appearance when worn.

Having described one embodiment of my invention, it is obvio is that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.

lVh-at I claim is 1. A watch case, a pair of spaced strips secured thereto and projecting from said case a bar connecting said strips, a wriststrap receiving casing having a hollow part inwhich said her is located, a flange on said casing bent over and enclosing the bar, and a cover plate secured over the bent-over flange and the bar.

2. A watch case having a separate wriststrap-receiving hollow end casing, said separate end casing containing a bar, a flange on said end casing bent over said bar, and several projections integrally formed on said bar, said projections extending out of the end casing and secured to the body of the watch case.

3. A watch case having an end casing, said casing comprising a hollow box-like section extending co-extensivcly with the end of the watch case and slightly spaced therefrom, several connecting strips extending between the end casing and the case, said connecting strips having a connecting cross-bar located and confined within the end ease, and a curled over flange on said end ease for confining the cross bar.

4. In watch case construction, a wriststrap holding member comprising a hollow elongated casing having laterally projecting ends a strap-receiving bar extending bet-ween and connecting said ends, a bar pivotally held within the casing by a bent over flange thereon, openings in said casing, and strips on said bar extending out of said openings and secured to the watch case.
